You can download the latest CloudFormation template from the Alces Flight Solo page on AWS marketplace.
Once you’ve got the template, you can add new CloudFormation resources to add a NAT gateway and update the VPC route resources to change how the VPC works to suit your requirements. Once you’ve created your modified CloudFormation template, use the CloudFormation console to create the stack as usual.
You’re probably not seeing any output from
nodeattr -n nodes as the command won’t show any results until compute nodes have started up.
Let us know how you get on – it’d be great to see the enhanced template you create and hear what you’re using Flight Compute for!
